[0003] But in recent years, it has been found that sycamore trees are extremely vulnerable to the pest damage of sycamore psyllids, whose nymphs and adults suck sap on the back of sycamore leaves or young tender trunks, destroying dredging Tissues, especially young trees suffer the most. In severe cases, the leaves of the whole plant will turn yellow and the tops will wither

The white cotton-like waxy substances secreted by nymphs block the stomata of the leaves, affecting the normal photosynthesis and respiration of the leaves, causing the leaves to appear pale and shriveled; when the wind blows, the white wax filaments flutter with the wind, like flying mist , seriously pollute the surrounding environment and affect the appearance of the city
